From Wikipedia
The name Onyx has sometimes been used, incorrectly, to label other banded lapidary materials, such as banded calcite found in Mexico, Pakistan, and other places, and often carved, polished and sold. This material is much softer than true onyx, and much more readily available. The majority of carved items sold as "onyx" today are this carbonate material.

Manikin, 2 years agoHey Bro I used to try then as a teen when I was late it never worked . Late meant a discipline action was in order for me !!! , you got away with more than me if that say'n saved you :-)

walksoftly, 2 years agoI remember there being times when my brother & I came home many hours past the time we should have been home. One time we came home at sunrise to find Mom sitting on the doorstep & I was driving the car but didn't have my license yet. My brother crawled out of the back seat & went straight in the house to bed & left me to explain to Mom where we had been & why I was driving. I don't remember any disciplinary action, she was just glad to see us home & alive. More than likely Dad put us to work a few hours later.
